'Application med February To all whom-'it may concern Be it known that I, SAMUEL W. DEcxERJ 'citizen of the United States, residing at; Jersey City, inthe county of Hudson andl State of-Newaersey, have invented certaing new and useful Improvements in Combined; Window Screens and Ventilators, of which the following `isa-specification. i ventnion relates to 4'new and useful,I improvements in Ventilating devices for;y windows and the object'of my invention is to providea ldevice which mayy be detach :ably engaged lin the window casing of ani ordinary window-and which will permit the.i opening of the window to as great an ex-f tent as desired and which will at the same time prevent a direct draft through the win- 4dow upon any one in the room. g A further 'object 'of'my invention is to sofI construct the device that even though the? window be open to its widest extent no rain orsnow can enter the room. And a still` further object of my invention is to provide; means'by which the entrance of all insects thrughthe open window will be prevented when 'the ventilator is in place.

With these and other objects in view, my invention will be more fully described, illustrated in the accompanying drawing and then specifically pointed out in the claims which are attached to and form a part of this application.

In the drawing, Figure l is a front elevation of a conventional form of Window con- 35. struction showing my ventilator in use. Fig. 2 is a vertical sectional view on 'the line'2-2 of Fig. 1; Fig. 3 is a transverse sectional view Von the line 3-3 of Fig. 1, looking downwardly; Fig. 4 is a fragmen- 40 tary sectional view taken on the line of Fig. 3,.showing the detachable mounting of the screen which forms a closure for the ventilaton Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the lsame reference `characters.

The construction and operation of the preferred embodiment of my invention can best be illustrated in connection with a window of the usual construction, such as shown in Fig. 1, including a window casing 10 having a window sill 11, yoke 12 and pulley stiles I3-each provided with the usual inner parting beads 14, -outer` parting beads 15 and in# termediate parting beads 16, between which the upper-andrlower window sas'hes 1.7'and .18 slide.

i ends slightly below thementral -iportion of .the wmdowcasing u fora reasonwhich :will be 'herelnafter fappa'rent.- These lribs or shoulders are preferably Aformed integrally with :the-parting beads-but in casetheventilaten-1s to .be applied to windows already .built and havingfthe usual type of parting bead, the ribs or shoulders may be Kfoi-med from-separatestrips of wood or metal secured to the parting bead. Furthermore, 1n connection -with the ventilator the sill of the window casingis preferably' provided with a strip of 'wood or metal 20 having an upwardly directed shoulder 21, this strip and shoulder forming 'in fact a horizontal continuation of the inner parting-beads and their shoulders. This strip is. not wholly essential but its employment is advantageous for reasons which will be explained.

The ventilator proper includes a substantially wedged shaped structure closed at its inner side, base and ends and open at its upper side and top. More particularly it includes an inner side member 22,'substantially triangular 4shaped side members or wings 23 and 'a 'horizontal base 24, these parts being so constructed that the wings converge slightly towardeach otherfat their free edges as clearly shown in Fig. 3 of the drawing, while the inner side'member 22 is inclined inwardly Ia'way `from the window 'from its lower to its upper end when the ventilator structure is 1n place. The free ledges of the wings 23 `are 'provided lwith laterally directed shoulders'or ribs 25 which vengage between "the shoulders of the parting beads 14 and the lower 'window sash. The base 24 `is also provided at its free edge with a downwardly depending rib` or-shoulder 26 which engages between the shoulder 21 andthe window sash.

As will be reudily'apparent from the foregoing description the interengagement fof the shoulders of the ventilator structure and the shoulders of the parting vbeads "serves l et - wings being to tirmly loclr the ventilating device in l place. Ait the same time the ventilator may.

e readily removed i'rom the window'basing by raising the same to bring vit aboveA the upper ends oi the shoulders 1.9 and so i'ree it from the casing. structure preferably terminates at its n per end ona level with the'mid portion otfthe window and it will therefore be apparent that the 'lower window sash may be raised to any desired extent and that all air entering throughthe window 'will'be dedected into the upper portion of the room bythe inclined inner side member or wall'22 or the ventilator. Because ot tbsany one in the -room will be thoroughly protected :from direct drafts throughF the window, llt will alsobe noted that any rain or snow driven through the'rwindow, winch would ordinarily enter the roormwill also strike'agai'nst 4the member .22` and"fwings and be turned back out oi the window. in this connection, the strip 20 and strip engagmgshoulder;

2610i the ventilator play an important' part in that 'they prevent vthe passage of any a'ir Vor moisture into the room beneath the :ventilaton Furthermore, they s'erve'izo space the base ofthe ventilator' slightly above the window sill in such a manner that 'the hand may be readily passed under the base' when the ventilator is to be removed vtrome the window. 'llhat portion 'of the ventilator' structure above described may be' formed of; any suitable material such as wood or metali Yand if desired, the inner side of said structuremay be formed 'of 'glass in order' to avoid shutting'light out of the room.' Y Foriv this reason l have illustrated the iront meme'E ber 22 in lFig. l as formed oi wood or metal;

while in Fig. 2 l have shown the use of a frame 2'? carrying a pane of 'glass 28ers, the inner member ot the ventilator.

ln order to'prevent all entrance oi in' sects into the room throughthe ventilator, when the window is open, ll'provide the np- 'perend or top of the ventilator' structure with a removable closure, indicatedV as a whole by the numeral 29; This closure in- -cludes'a trame' 30 covered with a screen oi ioraminons material, preferably wire screening, 3l. 'lihe ends ot this Aframe converge slightly toward each other as shown in Fig. 3 of the drawing, Jfor close engagement between the wings 23 of .the ventilator, the extended at their upper ends slightly above the top of the inner side member 22 tor this purpose. rihese extended portions ot" lthe wings are grooved horizontallyr as shown at 32 to receive tongues 33 termed along the end members oi the trame SOand it will therefore be apparent that the iframev may be readily slipped into or ont ot place in the ventilator. The inner hanne member is Vextended somewhat at'ite ends as showlnfat; it to Illbis ventilator against the upper engage against the inner edges' of the entended portions ont the 23 and. so stop the inward movement of' the elosii'e 29 and thus avoidgallfdanger of' brealning the glass of the window.. 70

.'ihe'konter member ot' .the closure frame 30 is rovided alon its onteredge with la paclnngstripfdot felt or rubber which,

when the closure is in place, engages against the glass of the lower. window sash to alo-175 solntely prevent-the entrance of 'insects to theroom. lit vthe window sashes are of that type in which two or more 'panes'of glass are mounted in each sash and. sf.apa'i'.atedby. one or more vertically entending'sash rails, 30 such as are shownat 36 in Fig. '3 et the drawing, the outer member ofthe frame will be notched as at 3'! to seat about the 'sash rail tof permit'the closure to bear snugly against the-window. f7* Y A 85 -lirom the torego'in description, -talren in :connection with the ravving, the' 'operation 'of my improved ventilatorwill be readily understood and any detaileddescription of the same is therefore unnecessary. lt'will 90 be noted howevenfthat when removing'the ventilator J.troni the window casingfthe elon sare l29 should'either be completely with-- drawn from 4the ventilator previous to rais-. f, ing the latter, or should at least be drawn o5 out to such a distance that it will not strike transverse sashl bar ot the :lower 'window sashnponraising ot the ventilatorszto ree-'itfrom its guides. i
